A new school for girls in India stays cool in 120 degree desert heat without air conditioning

The award-winning structure is a huge step forward for sustainable design.

Revolutionary school building stays cool even in 120 degree desert heat—with no air conditioning

Michael Daube, founder of the nonprofit CITTA, wanted to bring a school for girls to one of the most rural and conservative parts of India. In the region known as Rajasthan, the literacy rate for women was among the lowest in the country. There were few to no opportunities for girls to learn, and, for many, the only path in life was marriage.

There was just one problem with the plan: the rural desert community called Jaisalmer had almost no infrastructure to support a building that would meet the potential students' needs, and the nearest city was 40km away. Further complicating things, it would be challenging to build a low-tech outside venue for kids to learn in because of sweltering desert temperatures that routinely reach over 120 degrees Fahrenheit.

Luckily, architect Diana Kellogg was up to the challenge.

"I was so struck by Jaisalmer, the beauty of the place and how difficult it is to build in the climate," she told Stir World. "There was something very captivating about Jaisalmer and I also learned more about the situation of women and girls in that area. I was affirmed by the fact that education is better not just for individuals, but for the society as a whole. It changes the whole dynamic in societies."

She worked closely with the community to design the school, The Rajkumari Ratnavati Girls School, in a way that would empower women, give girls a safe place to learn, and stand up to the desert heat.

What's incredible is that the school building is able to stay relatively cool with no air conditioning even in the 120 degree heat using both ancient and local techniques:

  • Locally sourced sandstone gives the building its golden color and helps keep heat out of the interiors
  • Lining the inner walls with a material called lime plaster reduces humidity
  • A courtyard, which is customary in India, provides shade at many times throughout the day and can also be covered by a canopy
  • A jali wall—a grid-like structure—allows air to accelerate into the courtyard creating a breeze
  • High ceilings with window vents encourage hot air to escape
  • The elliptical shape of the building encourages air flow and allows high desert winds to flow around the structure

These techniques miraculously allow the indoor spaces to remain about 20-30 degrees cooler than the outside temperature.

The school building is also completely solar and wind powered, while a water harvesting system helps recycle the school's graywater and harvest fresh rainwater.

Not only does the sustainable building look and feel like an extension of its desert surroundings, it uses building techniques, materials, and technology that the girls in the region are familiar with. It's all designed to help them feel safe and unencumbered in their learning.

There are plans to expand the school in the near future, adding more buildings that will support a women's cooperative, a marketplace, a library, museum, and an exhibition space that will serve the extremely remote and rural community.

Kellogg and CITTA hope that the school can become a blueprint for more just like it around the world.

School is something many kids and families take for granted as a part of their communities, but there are plenty of areas like Jaisalmer where lack of infrastructure, poverty, and gender inequality keep kids from educational opportunities. In 2015, Global Citizen estimated about 60 million kids worldwide do not have access to a formal education. The Rajkumari Ratnavati Girls School is a wonder of modern architecture, but it also proves that it is possible through creative engineering to bring safe educational spaces to kids no matter where they live.

The building also won several architecture awards, including a prestigious recognition in the 2023 AIA Architecture Awards. It all helps get the word out.

"The comments that have come in are heart-warming. The girls find the space to be free and comfortable," Kellogg told Stir World. In a 2023 interview with CNN, she added that she's already seen a difference in the local girls who have attended school in the building she designed.

"[I've seen] the change in the girls, from being quite shy to being these bright lights that are devouring whatever kind of information you put in front of them."
